THEOPHILUS MILLOT AND JAMES MILLOT, OF NE'VV YORK, N. Y.

PROCESS OF TRANSFERRING A PRECIPITATED OR REDUCED METAL.

SPECIFICATION forming part of Letters Patent No. 345,442, dated July 13,1886.

Application filed Novembcr 18, [885. Serial No. 183,222. (Specimens) Toall whom it may concern.-

Be it known that we, THEOPHILUS MILLOT and J AMES MILLO'I, bothgof thecity, county, and State of New'York, have invented a new and ImprovedProcess of Transferring a Precipitated or Reduced Metal from a Plate tothe Face of a Sheet of any Flexible Material, of which the following isa full, clear, and exact description.

To carry our invention into effect we take a plate of any materialhaving a hard surface, but preferably employ a plate of glass, and as apreliminary step we clean the surface of the plate, after which we applyto the cleaned surface a mixture of soap and talc or soapstone, or anyother substance which will decrease the cohesion or affinity between theplate and the metal to be deposited thereon. After the application ofthe soap and talc or soapstone, or

other material, we wipe the plate, after which the metal to betransferred is precipitated upon the plate by any of the well-knownprocesses of precipitation. After the precipitation of the metal weapplya thin coating of glue, gelatine, or otherviscidstickysubstance,sueh coating being laid either on the precipitatedmetal or on the material to which the transfer is to be made, accordingto the circumstances of the case. In case the viscid substance isapplied to the precipitated metal, the treated surface of the plate iscovered with water ora proper liquid solvent after the viscid substanceis dry, and the material to which the transfer is to be made is thenplaced over the plate, the excess of liquid is expelled,'and the wholeleft to dry; but in case the viscid coat is applied to the material towhich the transfer is to be made such material is placed directly uponthe treated surface of the glass or other plate before the viscid coathas dried, and the material is in this case pressed firmly upon thedeposited metal, in order to exclude all air-bubbles. After the partsare apparently dry the plate,with its coverings, is heated by any propermeans, and then the material is seized and stripped from the plate whileit is still warm, and in operation it will be found that the metalliccoating will also be stripped from the plate and.will adhere to thematerial.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The herein-described process of transferring a metallic deposit,which consists in precipitating the metal upona hard surface, applyingthe material to be coated to such deposit, a coating of viscid substancebeing interposed, permitting the material to dry upon said metallicdeposit, slightly warming the whole, and then stripping the material anddeposit from the plate, substantially as de scribed.

2. The herein-described process of transferring a metallic deposit,which consists in precipitating the metal upon a hard surface, in thenapplying a coat of viscid substance to such deposit, flowing the plate,placing the ma terial to which the transferis to be made upon thetreated surface of said plate, expelling the excess of solvent, warmingthe whole, and stripping the material and the deposit from the surfaceof the plate, substantially as described.
